The distillation section is followed by two membrane separation sections operated in parallel, with the distillation section separating the feed mixture into an organics-rich fraction and an organics-depleted and solids-rich fraction. One membrane section operates on the organics-rich fraction and separates it into a more organics-rich sub-fraction and a water-rich, organics-depleted sub-fraction, while the other membrane section operates on the organics-depleted, solids-rich fraction from the distillation section and separates it into a solids-rich sub-fraction and a solids-depleted, water-rich sub-fraction.

  • Patent number: 7357849
    Abstract: A method and system for treating feedwater includes evaporating a portion of the feedwater in a first evaporation chamber so as to separate water vapor from the remaining feedwater. Droplets of the remaining feedwater are dispersed into a stream of hot air produced in a second evaporation chamber. The droplets evaporate and solids in the feedwater precipitate. The precipitated solids are collected in the lower section of the second evaporation chamber. Water vapor discharged from both evaporation chambers can be treated in a cyclone separator to remove residual solids therefrom. The cleansed water vapor output from the cyclone separator can be condensed to recover clean water. Dry solids can be discharged from the second evaporation chamber and the cyclone separator for recovery.

  • Patent number: 7163636
    Abstract: A multi-phase separation system utilized to remove contaminants from fluids includes a pre-filtering module for filtering a contaminated fluid to provide a filtered contaminated fluid. A condenser module receives the filtered contaminated fluid and a contaminated gas phase for condensing the contaminated gas phase to a contaminated liquid. A phase reaction chamber converts the filtered contaminated fluid to a contaminated mist wherein the mist is subjected to a low energy, high vacuum environment for providing a first change of phase by separating into a contaminated gas phase and a liquid mist phase. The contaminated gas phase is carried out of the phase reaction chamber by a carrier air. A vacuum pump provides the low energy, high vacuum environment in the phase reaction chamber and delivers the contaminated gas phase to the condenser module for condensation providing a second change of phase.

  • Patent number: 6417128
    Abstract: This invention relates to methods of replacing water and cyclohexanone with acetic acid in an aqueous solution of catalyst, preferably a cobalt compound. Such an aqueous solution is produced by extracting catalyst with water from a cyclohexanone/water solution of reaction products made by the direct oxidation of cyclohexane to adipic acid. The replacement of both water and cyclohexanone are conducted in a solvent exchange column, wherein acetic acid dissolves the catalyst, while water vapors force the cyclohexanone into a condenser, followed by a decanter wherein two liquid phases may be formed and separated; an upper liquid phase containing a majority of cyclohexanone and a lower liquid phase containing a majority of water. The cyclohexanone may be removed in a pretreatment zone, wherein also part of the water may be removed, before the concentrated catalyst extract enters the solvent exchange column.

  • Patent number: 6375803
    Abstract: A method and apparatus for removing a contaminant from a fluid feed stream containing the contaminant. The method includes the steps of providing a feed stream (10) and heating it in a first step (18) to at least partially remove some of the contaminants and recover energy from a concentrate and distillate generated. Further heating the feed stream in a second heating step (20) in a heated separator generates a saturated vapor fraction (30) and a concentrated liquid contaminant fraction. The vapor fraction (30) may be compressed (32) to generate a temperature differential in the reboiler exchanger (34) with the vapor fraction being passed into contact with a reboiler exchanger (34) to provide a stream of condensed vapor from the reboiler. The stream may be circulated through the reboiler exchanger (34) and the heated separator to maintain from about 1% to about 50% by mass vapor in the stream.

  • Patent number: 5958233
    Abstract: A new process and apparatus efficiently dewater aqueous solids residual after fermentation and distillation, such as corn stillage. The feed stream of aqueous solids slurry is fractionated into two or more substreams in such a way that one of the substreams contains predominately heavy particulate solids and has substantially improved free-draining characteristics. A second substream contains lighter particles, entrained fines of the heavy particles, and a major portion of the liquid from the feed stream. The free-draining substream is dewatered using a device such as a screen centrifuge or a screw press, both of which produce a cake of relatively high solids content. The remaining liquid from the feed stream is concentrated in an evaporator, before being mixed with the dewatered solids which may be dried to produce an animal feed.

  • Patent number: 5738761
    Abstract: A waste water treatment system includes a preliminary first stage separator for separating an aqueous phase from other materials. A pressure vessel sedimentation follows for removing most of the remaining solids from the waste material. The liquid and a minor fraction of the solids then pass on to an evaporation vessel where the water vapor is removed, compressed and passed through a condenser inside the evaporator vessel to recycle heat in the evaporator. The condenser is a stacked plate heat exchanger of unique design with the plates separated by steam gaskets and water gaskets to provide a very high heat transfer surface area to volume ratio. The condensate from the condenser passes through a second heat exchanger that heats the liquid flowing into the evaporator. The effluent water is purified by the evaporation. The residual solids may be heat treated to evaporate residual moisture and to sterilize the solids using a steam-jacketed auger. The resultant solids may be used as fertilizer.
